NASA Summer Camp Inspires Future Climate Leaders
From July 15-19, 2024, the Coastal Equity and Resilience Hub at the Georgia Institute of Technology collaborated with the University of Georgia (UGA) Marine Extension and Georgia Sea Grant to host a week-long NASA Sea Level Changemakers Summer Camp. The camp introduced 14 rising 7th-8th graders to how coastal areas are changing due to sea level rise. Set at the UGA Marine Education Center and Aquarium on Skidaway Island, the camp offered students hands-on activities and outdoor educational experiences, where they analyzed real data collected by NASA scientists and learned about community adaptations to flooding. Students interacted with experts from NASA’s Jet Propulsion Laboratory, UGA, and Georgia Tech, gaining insights into satellite observations, green infrastructure, environmental sensors, and careers related to sea level rise. The camp also included a visit to the Pin Point Heritage Museum, where students engaged with leaders from the historic Gullah Geechee community of Pin Point. The camp concluded with a boat trip to Wassaw Island, where students observed the effects of sea level rise on an undeveloped barrier island and compared these observations with earlier findings from urban environments. Funding from the NASA’s Science Activation Program and its Sea Level Education, Awareness, and Literacy (SEAL) team ensured that the camp was accessible to all students, eliminating financial barriers for groups traditionally underrepresented in STEM education.
“This investment from NASA has provided an amazing opportunity for youth in coastal Georgia to utilize NASA data and resources on a critical issue affecting their communities,” said Jill Gambill, executive director of the Coastal Equity and Resilience (CEAR) Hub at Georgia Tech. “They have more confidence now in their knowledge of sea level rise and potential solutions.”
The Sea Level Education, Awareness, and Literacy (SEAL) team is supported by NASA under cooperative agreement award number NNH21ZDA001N-SCIACT and is part of NASA’s Science Activation Portfolio.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A National Advisory Committee for Aeronautics researcher notes the conditions on the P-39L after its first test run in the Icing Research Tunnel on Sept. 13, 1944. The aircraft was too large to fit in the test section, so it was installed downstream in a larger area of the tunnel. The initial tests analyzed ice buildup on the nose, propeller blades, and antennae. In the summer of 1945, the P-39L was used to demonstrate the effectiveness of a thermal pneumatic boot ice-prevention system and heated propeller blades.Credit: NASA On Sept. 13, 1944, researchers subjected a Bell P-39L Airacobra to frigid temperatures and a freezing water spray in the National Advisory Committee for Aeronautics (NACA)’s new Icing Research Tunnel (IRT) to study inflight ice buildup. Since that first run at the Aircraft Engine Research Laboratory (now NASA’s Glenn Research Center) in Cleveland, the facility has operated on a regular basis for 80 years and remains the oldest and one of the largest icing tunnels in the world.
Water droplets in clouds can freeze on aircraft surfaces in certain atmospheric conditions. Ice buildup on the forward edges of wings and tails causes significant decreases in lift and rapid increases in drag. Ice can also block engine intakes and add weight. NASA has a long tradition of working to understand the conditions that cause icing and developing systems that prevent and remove ice buildup.
The NACA decided to build its new icing tunnel adjacent to the lab’s Altitude Wind Tunnel to take advantage of its powerful cooling equipment and unprecedented refrigeration system. The system, which can reduce air temperature to around –30 degrees Fahrenheit, produces realistic and repeatable icing conditions using a spray nozzle system that creates small, very cold droplets and a drive fan that generates airspeeds up to 374 miles per hour.
View upstream of the Icing Research Tunnel’s 25-foot-diameter drive fan in 1944. The original 12-bladed wooden fan and its 4,100-horsepower motor could produce air speeds up to 300 miles per hour. The motor and fan were replaced in 1987 and 1993, respectively.Credit: NASA Two rudimentary icing tunnels had briefly operated at the NACA’s Langley Memorial Aeronautical Laboratory in Hampton, Virginia, but icing research primarily relied on flight testing. The sophisticated new tunnel in Cleveland offered a safer way to study icing physics, test de-icing systems, and develop icing instrumentation.
During World War II, inlet icing was a key contributor to the heavy losses suffered by C-46s flying supply missions to allied troops in China. In February 1945, a large air scoop from the C-46 Commando was installed in the tunnel, where researchers determined the cause of the issue and redesigned the scoop to prevent freezing water droplets entering. The modifications were later incorporated into the C–46 and Convair C–40.
A National Advisory Committee for Aeronautics engineer experiments with an Icing Research Tunnel water spray system design in September 1949. Researchers used data taken from research flights to determine the proper droplet sizes. The atomizing spray system was perfected in 1950.Credit: NASA Despite these early successes, NACA engineers struggled to improve the facility’s droplet spray system because of a lack of small nozzles able to produce sufficiently small droplets. After years of dogged trial and error, the breakthrough came in 1950 with an 80-nozzle system that produced the uniform microscopic droplets needed to properly simulate a natural icing cloud.
Usage of the IRT increased in the 1950s, and the controlled conditions produced by the facility helped researchers define specific atmospheric conditions that produce icing. The Civil Aeronautics Authority (the precursor to the Federal Aviation Administration) used this data to establish regulations for all-weather aircraft. The facility also contributed to new icing protections for antennae and jet engines and the development of cyclical heating de-icing systems.
The success of the NACA’s icing program, along with the increased use of jet engines – which permitted cruising above the weather – reduced the need for additional icing research. In early 1957, just before the NACA transitioned to NASA, the center’s icing program was terminated. Nonetheless, the IRT remained active throughout the 1960s and 1970s supporting industry testing.
The Icing Research Tunnel is highlighted in this 1973 aerial photograph. The larger Altitude Wind Tunnel (AWT) is located behind it, and the Refrigeration Building that supported both tunnels is immediately to the left of the AWT.Credit: NASA By the mid-1970s, new icing issues were arising due to the increased use of helicopters, regional airliners, and general aviation aircraft. The center held an icing workshop in July 1978 where over 100 icing experts from across the world converged and lobbied for a reinstatement of NASA’s icing research program.
The agency agreed to provide funding to support a small team of researchers and increase operation of the icing facility. In 1982, a deadly icing-related airline crash spurred NASA to bring back a full-fledged icing research program.
Nearly all the tunnel’s major components were subsequently upgraded. Use of the IRT skyrocketed, and there was at least a one-year wait for new tests during this period. In 1988, the facility operated more hours than any year since 1950.
This model was installed in the Icing Research Tunnel in 2023 as part of the Advanced Air Mobility Rotor Icing Evaluation Study, which sought to refine testing of rotating models in the tunnel, validate 3D computational models, and study propeller icing issues.Credit: NASA The facility was used in a complementary way with the Twin Otter aircraft and computer simulation to improve de-icing systems, predictive tools, and instrumentation. IRT testing also accelerated the all-weather certification of the OH-60 Black Hawk helicopter. In the 1990s, the icing program turned its attention to combatting super-cooled large droplets, which can cause ice buildup in areas not protected by leading edge de-icing systems, and tailplane icing, which can cause commuter aircraft to pitch forward.
The IRT was one of the busiest facilities at the center in the 2000s and continues to maintain a steady test schedule today, investigating icing on turbofan engines and propellers, refining testing of rotating models, validating 3D models, and much more. The IRT been used to develop nearly every modern ice protection system, provided key icing environment data to regulatory agencies, and validated leading ice prediction software. After 80 years, it remains a critical tool for sustaining NASA’s leadership in the icing field.

7 Min Read NASA Project in Puerto Rico Trains Students in Marine Biology
A forested green peninsula of Culebra Island juts into the blue waters of the Caribbean as a rain storm hits in the distance. The teal blue surrounding the island indicates shallow waters, home to the island's famous coral reefs. Credits: NASA Ames/Milan Loiacono Tainaliz Marie Rodríguez Lugo took a deep breath, adjusted her snorkel mask, and plunged into the ocean, fins first. Three weeks earlier, Rodríguez Lugo couldn’t swim. Now the college student was gathering data on water quality and coral reefs for a NASA-led marine biology project in Puerto Rico, where she lives.
“There is so much life down there that I never knew about,” Rodríguez Lugo said. “And it’s beautiful.”

OCEANOS 2024 Intern
The sea whip and purple sea fans in the photo above are found off the coast of Playa Melones, Culebra, a small island off the east cost of Puerto Rico and a popular destination for snorkelers.
Puerto Rico is home to more than 1,300 square miles of coral reefs, which play a vital role in protecting the island from storms, waves, and hurricanes. Reef-related tourism provides nearly $2 billion in annual income for the island.
But coral reefs in Puerto Rico and around the world are experiencing more frequent and severe bleaching events. High ocean temperatures in regions around the globe have led to coral bleaching, which is when corals expel zooxanthellae – the colorful, symbiotic microscopic algae that live inside coral tissues and provide 80-90% of its nutrients. When stressors persist, the corals eventually starve and turn bone-white.
In April 2024, NOAA (National Oceanic and Atmospheric Administration) announced that the world was experiencing a global bleaching event, the fourth on record. You can see bleached spots in the lobed star coral pictured above, which is also colonized by Ramicrusta, an invasive, burnt orange algae that poses an additional threat to reefs.
Students Are Given Ocean Research Tools
Beginning in June, the month-long program that Rodriguez and 29 other local students participated in is called the Ocean Community Engagement and Awareness using NASA Earth Observations and Science for Hispanic/Latino Students (OCEANOS). The goal of OCEANOS is twofold: to teach Puerto Rican students about marine ecology and conservation, and to train students through hands-on fieldwork how to use marine science tools to monitor the health of coral reefs.
The course included classroom instruction, scientific fieldwork, collecting and analyzing ocean data from La Parguera and Culebra Island, and a final presentation.
In the photo, OCEANOS instructor Samuel Suleiman shows a 3D-printed clump of staghorn coral to a group of students off the coast of Culebra. In areas where coral habitats have been damaged, conservationists use 3D-printed corals to attract and protect fish, algae, and other wildlife.
To practice coral surveying techniques and evaluate biodiversity,students used compact cameras to snap a photo every half second, recording seven-meter by seven-meter quadrants of the ocean floor. Back on land, the students stitched these images – roughly 600 images per quadrant – into high-resolution mosaics, which they then used to catalog the types and distributions of various coral species.
Low Light, Poor Water Quality, and Invasive Species Threaten Coral Reefs
Students also built their own low-cost instruments, with sensors on each end to measure temperature and light, to help assess water quality and characteristics.
The ideal temperature range for coral falls between 77- 82 degrees Fahrenheit (25-28 degrees Celsius). Water above or below this range is considered a potential stressor for coral and can impair growth. It can also increase the risk of disease, bleaching, and reproductive issues.
Coral relies on light for growth. Less light means less photosynthesis for the zooxanthellae that live inside the coral, which in turn means less food for the coral itself. Cloudy water due to excessive sediment or phytoplankton can dim or block sunlight.
Additional threats to coral include fishing equipment, boat groundings, chemical runoff, and invasive species.
In the photo above, OCEANOS instructor Juan Torres-Pérez holds two clumps of cyanobacteria, a type of bacteria that has choked a section of reef near Playa Melones. The exact cause of this excessive cyanobacteria growth is unclear, but it is likely due to land-based pollution leaching into nearby waters, he said. In the background, dark brown piles of cyanobacteria littering the ocean floor are visible.
Students Help Grow and Plant New Coral
Suleiman walked students through the process of planting new coral, which involved tying loose staghorn and elkhorn corals into a square frame. Each frame holds about 100 individual pieces of coral. Suleiman leads a group called Sociedad Ambiente Marino (SAM), which has been working for more than 20 years to cultivate and plant more than 160,000 corals around Puerto Rico.
Divers anchored these frames to the ocean floor. Under ideal conditions, branching species like elkhorn and staghorn coral grow one centimeter per month, or about 12-13 centimeters per year, making them ideal candidates for coral reef restoration. By comparison, mountainous and boulder coral, also prevalent in the Caribbean Sea, grow an average of just one centimeter per year.
The frames will remain on the ocean floor for 10 to 14 months, until the corals have quadrupled in size. At any given time, SAM has about 45 of these frames in coral ‘farms’ around Culebra, totaling almost 4,500 corals.
Once the corals are ready to be planted, they will be added to various reefs to replace damaged or bleached corals, and shore up vulnerable habitats.
In the photo above, Suleiman gathers loose corals to place around an endangered coral species Dendrogyra cylindrus, more commonly referred to as Pillar Coral (front left). This underwater “garden,” as he called it, should attract fish and wildlife such as sea urchins, which will give the endangered coral — and the other species in this small reef — a better chance of survival.
A New Generation of Marine Scientists
From the 2023 OCEANOS class, roughly half of the undergraduate students went on to pursue marine science degrees, and many hope to continue with a post-graduate program. For a scientific field historically lacking diverse voices, this is a promising step.
Among the high school students in the 2023 class, three went on to change their degree plans to oceanography after participating in the OCEANOS program, while others are finding ways to incorporate marine science into their studies.
Francisco Méndez Negrón, a 2023 OCEANOS graduate, is now a computer science student at the University of Puerto Rico at Rio Piedras and wants to apply robotics to marine ecology. “My goal is to integrate computer science and oceanography to make something that can contribute to the problems marine ecosystems are facing, mostly originated by us humans,” Méndez Negrón said. He returned to the OCEANOS program to serve as a mentor for the 2024 class.
As for Tainaliz Marie Rodriguez Lugo, she managed to overcome her swim anxiety while discovering a love of the ocean. She credited the instructors who were patient, encouraging, and never left her side in the water.
“I was really scared going into this internship,” Rodríguez Lugo said. “I didn’t know how to swim, and I was starting a program literally called ‘Oceans.’ But now I love it: I could spend all day in the ocean.”

When asked how she would describe coral to someone who has never seen one, Rodríguez Lugo just laughed. “I can’t. There are no words for it. I would just take them to the reefs.”
